To all whom it may concern:

Be it known that 1,. Canvas M. VAN HEUSEN, a citizen of the UnitedStates, residing at Albany, in the county of Albany, State of New York,have inventedcertam new and useful Improvements in Chime Attachments forI do hereby declare th8*f( )llO W1I1g to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same. i

This invention, like the one disclosed in my application filedconcurrently herewith, is directed to the production of an attachmentfor the signal boxes employed in connection with telephone call bellsystems, the attachment being adapted to be substituted for the usualhammer and gongs of such bells, to produce a vibrating sound of pleasingpitch and timbre, capable of variation in tone and effect, instead ofthe harsh, sound vided for adjusting the startling.

production of an attachment for suc signals, will heretofore producedwith a vi giving an alarm.

The usual telephone call box is one inclosing an electromagnet andhaving an opening in the top through which the stem of a vibratoryhammer prolects, and also having gong posts pro ecting upwardly from thetop on opposite sides of the hammer and adapted to support gongs. tionof the hammer causes it to strike the two gongs. alternately but thesound emitted is a harsh, strident and umnusical sound which isdisagreeable and unnecessarily ew solely to to the a call box, speciallyconstructed so as to facilitate mounting it in position 'WltllOlltdisturbing or altering the parts of the signal box other than by theremoval of the gongs, whereby pleasing musical sounds, equally effectiveas be substituted for the strident and unmusical sounds of the ordinaryalarm. The attachment whereby this end is accomplished consists of astriker adapted to be securely mounted upon the end of a hammer of thetelephone signal box, without requiring' any change in the hammer oraffect ng its vibratory movement, a frame extending upwardly from thegong posts and detachably fastened thereto, and one or more elon gatedbells suspended from the frame in cooperation with the striker, meansbeing probelltoward and The present invention is directe TelephoneSignal-Boxes; and

different lengths to simulate chimes.

away from the striker. Preferably the bell is fastened to the frame inadjusted position relatively to the striker, and the frame may befastened to the gong posts of the telephone box in adjusted position. Inthis way provision is made for adjustment of the signal apparatus'topermit ofthe minute regulation seemingly required for the effect desiredunder the particular conditions existing in almost every individualcase. So, also, the striking surfaces of the striker are padded orotherwise constructed to eliminate or reduce the metallic sound socommon 1n.

telephone signal apparatus as at present coning tone, and where two areprovided on opstructed. The bells are preferably elongated tubes ofglass or-a bell metal having a pleasposite sides ofthe striker, they maybe of In the preferred construction hereinafter described, a resilientrod is fastened at one end to the bell and terminates at the other endin a ball weight, whereby when the bell is vibrated by impact with thestriker, the rod is also set into vibration and results inthe productionof a waving sound or cres-' cendo effect. 7

These devices may have various forms in accordance with my invention, asappears in the accompanying drawings, in which,

Figure 1 is'an elevation, partly in section, of the preferred form ofthe invention; Fig. 2 is a section on line 22 of Fig. 1; Fig. 3 is anelevation partly in section, showing a modified form of the frame; Fig.4 is a perspective View of a yoke for supporting the bell;Fig. 5 is aperspective view of a further modified form of frame; Fig. 6 is aperspective view of the lower portion of still another form of frame;and Fig. 7 is a perspective view of a frame wherein a single bell may beadjusted in position both vertically and laterally toward and away fromthe striker.

In all of the. embodiments of the invention illustrated in the drawings,the usual form of telephone box is shown at 1. This box has an openingin the top through which projects the hammer 2 which is adapted to bevibrated rapidly by an electromagnet located within the box. On oppositesides of the vibratory hammer are posts 3 mounted stationarily upon thetop of the box and projecting upwardly therefrom. The upper ends of theposts 3 have threaded'openings in them, and in the ordinary form ofsignal box the gongs are mounted on these posts on, opposite sides ofthe hammer by screws entermg the threaded openings in the posts.

The attachments constituting the resent invention consist of a striker4secure to the ball end of the hammer 2, and one or more elongated chimebells, such as tubes of glass or of bell metal of pleasing sound. Thestriker may be adjustable toward or away from the bell or bells, as ismore fully described in my copending application herein referred to,although, in this application, I show a divided striker 4, the parts ofwhich are adapted to be screwed .together into clamping engagement withthe ball end of the hammer, and to be held in clamped position by alocking screw. The striking surface or surfaces of the striker arecovered with leather, ebony, ivory, cork, or other material to eliminateor reduce the metallic sound upon impact with the bells .The bell orbells areeesuspendeii from a frame extending above thegongpgsts 3, andfastened thereto in any suitable way. Inall cases shown herein the bellsare adjustable in minute increments toward and away from the striker bylaterally adjusting the bells in ositionin the frame, or by adjustin therame in relation to the gong posts, or th. In Fig. 1 the frame 5consists of a fiat metal strip perforated and bent into a partly closedrectangular form. The feet 6 have elongated slots 7 through which extendthe posts 3 of the usual form of telephone signal box, thereby providinglateral adjustment. he frame is secured in adjusted lateral position bymeans of caps 8, which are screwed on the posts 3. The two bells 9 and10 are tube-shaped and of differentlengths to simuber coverings l6surrounding the posts, p relate chimes. Each is suspended from the.frame by means of a yoke 11 which, as shown best in Fig. 4, has seats 12for the laterally extendin posts 13,, and pivoted latches 14 arrange tori idly hold the posts to their seats. Felt was hers 15 around the posts13 between the yoke and bell, and rubvent any su stantial suppression ordam mg by the support of the vibration of the bell. 'lhe yoke isfastened in adjusted position in an elongated slot 18 of the uppercross-bar 19 of the frame by means of the screwthreaded rod 20 and thenuts 21, this arrangement permitting a limited vertical adjustment ofthe yoke as well as a lateral adjustment thereof. As shown best in Fig.2, a rod is fastened to the crown of the bell and has a resilientportion 22 terminating in a weight 23 so that the rod and weight are setinto vibration by the vibration of the bell and thereby produce a Wavingsound or crescendo efl'ect.

' The construction of the embodiment shown in Fig. 3 is similar to thatof Fig. 1 in many respects. The principal difference is that the frame24 is not adjustable relatively( to the gong posts 3, but terminates incaps 25 adapted to'set over the gong postsand to beffastened thereto bscrews 26.

In Fig. 5, the frame 27 as feet 28 with open-ended slots 29 and acontinuous slot 30 in the cross-oar 31 to u'ovide more lateraladjustment than in the embodiments of Figs. 1 and 2.

In Fig. 6, the frame 32 is provided with feet 33, each having a hole 34adapted to set snugly over a gong post and to thereto by a cap or othersditable means.

The frame 35 shown in Fig. 7 is adapted for supporting a single bell. Ithas a vertical slot 36 whereby the bracket 37 may be fastened to theframe ir vertically adjusted e secured position. This bracket has anelongated slot 38 for lateral adjustment of the bell toward and awayfrom the striker.

In the drawings, various constructions are illustrated in which theparts constituting the attachment of the )resent invention may beembodied, and it Wlll be understoodthat other constructions differentfrom those illustrated may be employed if desired. In all cases,however, it will be noted that the attachment consists of a striker ad:ted to be attached to the ball hammer of t is telephone signal boxwithout requiring any change or substitution therein, and a laterallyadjustable bell or bells coiiperating with the striker and suspended inposition from a support arranged to be secured to the stationar threadedposts of the telephone box. he frame may be laterally adustablerelatively to the gong osts, and the bell or bells may be-vertical yadjustable relatively to the striker. In all of these various forms ofconstruction, the adjustment provided permits regulation of the bell orbells toward and away from the striker in minute increments to regulatethe sound produced as may be found desirable.
